The 11th Army (German: 11. Armee / Armeeoberkommando 11 / A.O.K. 11) was an army level command of the German Army in World War I. It was formed in March 1915 in Kassel originally to serve on the Western Front but was transported to Galicia for service on the Eastern Front. The army was dissolved on 8 September 1915, but reformed on 23 September 1915 for the Serbian Campaign. It was finally dissolved on 7 January 1919.
The 11th Army was formed in early 1915. It briefly fought on the Western Front during the Battle of Ypres, holding the line against the Allied attack. On 22 April, it was transferred and placed with the Austrian 4th Army under Mackensen's command, behind the Gorlice–Tarnow gap, south of the Vistula River. In July 1915, the 11th Army advanced into Russian territory in a general German offensive. The 11th Army was dissolved on 8 September 1915.
On 23 September 1915 a new 11th Army was created for the Serbian Campaign under command of Max von Gallwitz. It was composed of the III Corps, the IV Reserve Corps and the X Reserve Corps. After the defeat of Serbia, the 11th Army remained on the Salonika Front in support of the Bulgarian Army.
